Variations of this command include:
ppp multilink
ppp multilink fragmentation
ppp multilink interleave
ppp multilink maximum <number>
Syntax Description
fragmentation
interleave
maximum <number>
Default Values
By default, MLPPP is disabled.
Command History

Release 7.2
Release 11.1
Functional Notes
When enabled, this interface is capable of the following:
•
Combining multiple physical links into one logical link.
•
Receiving upper layer protocol data units (PDUs), fragmenting and transmitting over the physical links.
•
Receiving fragments over the physical links and reassembling them into PDUs.
The fragmentation and interleave options can be used to enhance the multilink operation. Fragmentation is
used to reduce serialization delays of large packets. The fragmentation process evenly divides the data
among all links in the bundle with a minimum packet size of 96 bytes. The interleave operation is used with
streaming protocols to reduce delay by giving priority to packets identified as being high priority. Delivery in
order is guaranteed with multilink fragmentation, but is not guaranteed with multilink interleave operation.
The multilink bundle will remain active with a minimum of one physical link. Physical links may be
dynamically added or removed from the multilink bundle with minor interruption to traffic flow.
